摘要: 选用木质素含量效高,具有较强吸水能力的物质如麦糠、棉子皮、棉铃壳等作为有机吸水物,每年结合整地施入土壤,每HM2施用7500KG即有明显效果:(一)提高土壤的蓄水和渗水能力,增加土壤的含水量,从而在根层土壤处形成一个"小水库",利于形成"丰水蓄,旱季补"的田间地表水与土壤内部水的良性循环.(二)连续几年施用上述有机吸水物质,能有效地提高耕层土壤有机质含量,并改善了土壤结构,尤其适于既旱又薄的棉田.(三)改善了棉株功能叶的水分营养状况,利于防止棉花后期早衰.经方差分析增产效果达到了0.05的显著水平.
英文摘要: Some materials which are rich in lignin and have higher ability of ater absorption,such as wheat glumes, cotton seed shells and rotten boil hulls, can be used as water absorption materials in dry cotton fields. Applying 7500kg water absorphon materials to soil with soil tillage per hatre per year has the following cffects: (1)Improve soil ability of impound, soil moisture permeability and increase soil moisture content. Especially the soil moisture content around root area can be increased by 2 ̄3 percent po...
